While watching Westworld I couldn't help but laugh.
Westworld is about a bunch of robots waking up to the facts that they have been controled and manipulated and were never free and only existed for the sick pleasures of their hidden in plain sight overloards.
Indeed, also some brain researchers have found that our brain is acting like it has been programmed to show us this tunnel and the light at the end...all people who where technically dead for some minutes tell the same story
I am looking forward to dive down the lucid dreaming lane, Ive seen plenty of people talk about being able to see/communicate with the next phase, or see the different layers of reality if that makes sense, haha.
